Description
RO 1 Receiver Output. When enabled, if A > B by 200 mV, then RO = high. If A < B by 200 mV, then RO = low.
RE
2
Receiver Output Enable. With RE low, the receiver output (RO) is enabled. With RE high, the output goes into a
high impedance state. If RE is high and DE is low, the ADM3485E enters a shutdown state.
DE 3
Driver Output Enable. A high level enables the driver differential outputs A and B. A low level places it in a high
impedance state.
DI 4
Driver Input. When the driver is enabled, a logic low on DI forces A low and B high, while a logic high on DI
forces A high and B low.
GND 5 Ground Connection, 0 V.
A 6 Noninverting Receiver Input A/Driver Output A.
B 7 Inverting Receiver Input B/Driver Output B.
